legislature tried to reverse the course set by the PUC by passing a bill to roll back the PUC's decision to phase down net metering. The bill passed the legislature but was vetoed by Governor Paul LePage. Massachusetts Massachusetts law allows net metering for any kind of generation technology (even non-renewable), up to 60 kW in capacity. Solar, wind, and anaerobic digestion facilities are eligible for much higher caps, depending on whether they are privately or publicly owned. Privately owned generation facilities must be under 2 MW and publicly owned under 10 MW. The total cap on net metering was established in state law in April 2016. For the private sector, it set the cap at 7% of historic peak load. For the public sector the cap is 8% of historic peak load. These values are calculated for each electric company in the state. This means, the net metering cap is different in different parts of that state (served by different electric companies). For example, the cap for private generation on Nantucket is only 3.5 MW, but for western Massachusetts it is 59.78 MW. In January 2018, the Massachusetts Department of Public Utilities (DPU) approved demand charges for Eversource utility's net metering customers. DPU also got rid of optional time-of-use rates for residential customers. Among renewable and clean energy advocates, demand charges are "very controversial." DPU's decision has set the stage for intense debate over rate design. Eversource had argued it faced "displaced distribution revenues" of more than $8 million per year that should be collected from net-metered customers. The DPU agreed, saying "the companies have demonstrated a cost shift from net metering to non-net metering customers by identifying costs directly imposed by net metering facilities on the distribution system." Michigan In June 2018, the Michigan Public Service Commission decided to end net metering for new solar installations. Existing residential solar customers would have ten more years of net metering. Companies that install solar panels expect that the new policy will hurt their business. Michigan utility companies such as Consumers Energy and DTE Energy argue that other customers are subsidizing the customers [who have] solar. According to Michigan NPR, utility companies "say paying solar customers the retail rate for power ignores the utility companies’ costs of maintaining the power lines and the power plants that provide the minimum baseload required to keep the power operating."
